UNIT FEATURES
Fig. 2 – E-TAC Front Panel
This E-TAC has many exciting features which
are different than those found on standard PTAC
models. The owner must be familiar with these
features in order to fully understand the operation and
capability of the unit.
• Intelligence – Your E-TAC unit has an on board
computer that utilizes real time diagnostics toprolong
the life of your unit. There is an LED indicator on the
control board, behind the front panel, that will flash
an error code if the unit has detected some kind of
fault condition. In many cases, the unit will
automatically clear th
operating with no interruption. In some cases, the
condition cannot be cleared and the unit will require
service. In those cases, an “Fx” failure mode will be
displayed on the digital display. For a detailed list of
all error codes and “Fx” conditions, see Table 6 -Status LED Indicator Definitions for further details.
• Memory – Your E-TAC unit also has memory. If
power is lost, all of the control settings (setpoint,
mode, fan speed, on/off and configuration) are
remembered. So when power is
start back up in the mode (and configuration) it was
in, when power was lost.
• Premium Sound – Your Premium E-TAC is also the
quietest PTAC ever. Not only does it have 2 fan
motors and a tangential blower wheel for optimum
sound, the indoor fan will always run a minimum of 10
seconds before the compressor, to help reduce any
compressor starting noise.
• Random Compressor restart -- To help prevent
power surges after a power outage (from many of
your E-TACs starting at the same time), the
compressor is equipped with a 2:45 to 3:15 random
restart delay feature. Whenever the unit is plugged in,
or power has been restarted, a rand
restart will occur.
• Dry Mode – will help to manage and reduce the
humidity in the room, making it more comfortable. In
DRY mode, the unit will modulate cooling mode at
low fan speed until the room temperature is 4 deg. F
e fault condition and continue
restored, the unit will
om compressor
below the room temperature setting regardless of fan
mode selection. Dry mode should not be considered a
substitute for a stand alone dehumidifier.
• Compressor Protection -- To prevent short cycling
of the compressor and maximize
it’s life, there is a
random start--up delay of 3 minutes on the
compressor and a minimum compressor run time of 3
minutes.
• Automatic room freezeprotection – automatically
will keep the temperature in the room from getting
too cold, where water pipes might freeze. If the unit
is configured for the freeze protection feature to be
active (which is the default condition), then whenever
power is supplied to the unit, if the unit senses
temperature below 40°F (4.4°C), the fan motor and
electri
c heater are turned on and will warm the room
to 50° F (10°C). If Freeze protection is not required,
change the configuration switch to turn the feature off
(see section on unit configuration).
• Automatic defrost protection (for heat pump
models only) – When the outdoor temperature gets
too cold (approx. 40°F / 4.4°C) and the unit can no
longer effectively heat wit
h the compressor, the unit
will automatically switch to electric heating. The unit
will then heat with electric h
eat until the outside
temperature rises enough (approx. 40°F / 4.4°C), so
the compressor can be used again.
• Automatic Quick Warm--up (for heat pump
models only) -- If the room temperature falls to 5°F
(2.8°C) below the set point temperature, the reverse
cycle heat is shut off and the electric strip heat is
turned on for one cycle, until heating is satisfied.
• LED Indicator’s and Buttons -- The touch pad has
buttons for MODE, FAN SPEED, ON/OFF,
SETPOINT UP and SETPOIN
T DOWN. I
t also has
LEDs that correspond to the mode, fan speed and
setpoint operation, to indicate the unit’s status. The
LEDs below the mode button, FAN, COOL, and
HEAT, indicate what operating mode is active. The
LEDs below the Fan button, Low, Med and Hi,
indicate the fan speed that is selected. The LED
located in the lower right corner is the unit On/Off
status LED. If the unit is in ON mode, the LED will
be green. If the unit is OFF, the LED will be red.
• Configure Fan to Optimize Selected Application
–
Unit can be optimized to selected application by
configuring
the fan to run in continuous mode or cycle
on and off with the compressor and electric heater (can
be different for both heating and cooling modes). In
cycle mode, fan will continue to run 60 seconds after
compressor or electric heater stops in order blow off
any residual heat or cool left on coil.

UNIT FEATURES CONTINUED
• Unit Configuration – There are many different
configuration possibilities, through both dipswitches
and the digital keypad, that allow you to configure
the unit for your exact application. See section on
unit configurationfor more details. Following are the
configuration selections that havenot previously been
mentioned:
• Fahrenheit °F or Celcious °C – The unit can display
in either °F or °C.
• Indoor Temperature Sensor Biasing – Optimize
the room temperature sensor reading to your exact
application (one for cool
ing and another for heating).
• Emergency Heat (for Heat Pump Only) – Disable
the compressor during heating mode operation (heat
only with Electric Heat).
• Display Setpoint or Room Temperature -- The
unit can be configured to display the room
temperature OR setpoint only, during heating and
cooling modes. See section on unit configuration for
more details.
• Limit the Setpoint Range -- The unit can be
configuredto limit the controlling setpoint range. The
display will always show the completesetpoint range,
but the
controlling setpoint will be limited to the
configuredminimum andmaximumsetpoint selected.
See section on unit configuration for more details.
• Energy Management – Sometimes known as
Front Desk Control, an input is provided so that the
unit ca
n be manually disabled from a different
location. If the unit detects 24vac on this input, it will
automatically turn itself off. If no voltage is detected
on the input, the unit will run normally.
• Wall Thermostat Control – A wired wal
thermostat can be connected to the unit. If it is, the
unit must be configured to disable the keypad. See
section on wired inputs and unit configuration for
more details.

injury or death and/or property damage
DO NOT alter cord or plug or use an extension cord.
IMPORTANT: For 265V units, if power cord
accessory option is selected, the cord is only 18 inches
long and must plug into the accessory electrical
265V subbase.
Be sure that your outlet matches the appropriate blade
configuration of the plug and that it is within reach of
the service cord.
All wiring, including installation of the receptacle,
must be in accordance with the NEC and local codes,
ordinances and regulations. National codes require
the use of an arc fault or leakage current detection
device on all 208/230V power cords. Be sure to selec
the correct cord for your installation.
ALL UNITS
Wire Size
Use recommended wire size given in Table 1 and
install a single branch circuit. All wiring must

INSTALLATION
Proper installation is the responsibility of the
installer.
Product failure due to improper installation is not
covered under the Warranty.
CHASSIS INSTALLATION
Units are shipped without a sleeve. In applications
where unit is a replacement, it is recommended that a
Gree sleeve be used.
These units can retrofit Carrier, General Electric,
Amana, Trane, and Friedrich sleeves/grilles (be sure
outdoor grille is installed on the sleeve). See Table 3
for details. Gree engineering must approve any other
retrofit application.
For competitive retrofit applications, be sure that the
foam seals (factory-installed on the tube sheets)
provide a good seal between the grille and outdoor coil
tube sheets. These foam seals provide a barrier to
separate outdoor coil leaving air from mixing with
the outdoor incoming air (known as air recirculation).
!
CAUTION
UNIT DAMAGE AND/OR OPERATION HAZARD
Failure to follow this caution may result in equipment
damage or improper operation.
For retrofit applications, foam seals on outdoor coil tube
sheets must make a seal between the coil and the grille or
loss of performance and premature damage to the major
components can result.

INSTALLATION OF A GREE WALL
SLEEVE USING A NON--GREE GRILLE
This application has become more common due to
pre-manufactured windows with built-in grilles or
renovations where a Gree sleeve is used with an
existing non-Gree grille.
Use of a Gree wall sleeve with a non-Gree grille
requires installation of an Accessory Baffle Kit (see
Fig. 7), which ensures a good seal between the unit
and exterior grille to prevent air recirculation. Air
recirculation is a large contributor to performance
loss and prema
ture damage to major components.
Fig. 6 – Remove Bottom Seal From GE Plastic Sleeve
Fig. 7 – Accessory Baffle Kit
CONDENSATE REMOVAL SYSTEM
Gree’s series has a new condensate (water) disposal
system. The outdoor fan prop has a built in slinger
ring which draws condensate water and sprays it on the
warm outdoor coil for evaporation. Thus providing
better disposal of excess condensate and improving
unit operating efficiency.
It is normal and desirable to have some condensate
water in the base pan to boost operating efficiency.
All heat pump units contain a condensate drain
valve. This temperature activated drain valve opens
when the outdoor temperature drops below 55˚ F
(12.8˚ C) to prevent water from freezing in the base
pan. The water drains from the unit tho
sleeve and out the wall sleeve’s rear condensate
drainage holes. If the condensate drain kit accessory
is attached to the wall sleeve, water will drain
through the condensate drain tube.
NOTE: This unit will not always evaporate 100%
of the unit generated condensate and blown in
rain water. If it is necessary to control 100% of
the condensate, the Drain Kit (Part No.: DRAINKIT-1PK) and a building condensate drain
system is recommended.
